为了获得什么样的外部节奏呼吸是舒适的基本信息，25名男性和25名女性本科生被要求练习自我节奏呼吸。受试者按照指示进行1分钟的舒适自主呼吸练习后，进行2分钟的自主呼吸，并对自己的舒适程度进行1-5分的评分。这一过程被重复（最多七次），直到受试者得到高评分。结果表明，当呼吸模式达到呼吸频率的一半和潮气量的近两倍时，自我节律呼吸是最舒适的，与性别无关。虽然呼吸性窦性心律失常和心率表明心脏迷走神经活动减少，潮末二氧化碳分压表明焦虑减少，但这些影响很小。研究结果对体外节律呼吸的应用具有启示意义。
In order to obtain basal information about what type of externally paced respiration is comfortable, 25 male and 25 female undergraduate students were asked to practice self-paced respiration. After a 1-min rehearsal following instructions on comfortable self-paced respiration, subjects carried out 2 min of self-paced respiration and rated their level of comfort on a scale of 1–5. This was repeated (up to a maximum of seven times) until the subject recorded a high rating. Results indicated that self-paced respiration was most comfortable, irrespective of sex, when a respiratory pattern was attained of half the respiratory rate and nearly twice the tidal volume of the trainee's resting condition. Although respiratory sinus arrhythmia and heart rate were indicative of a decrease in cardiac vagal activity and end-tidal PCO2 was suggestive of a reduction in anxiety, these effects were small. The results have implications for the utilization of externally paced respiration.
